Stordy/Hauck gas burners of Ferro enameling furnaces are operated with cold combustion air and have therefore low NOx emissions.
These burners may run “forever” provided their setting are regularly checked and when applicable adjusted.
In case of any damage, we may provide all necessary spare parts for such burners.
See http://industrial-enameling.shop for more info.
Last week we assisted a customer in the United Kingdom with replacing all radiant tubes of their vitreous enameling furnace. Continue reading “Replacement of radiant tubes”
Flow-coating is a very efficient method, which is frequently used for applying wet enamels on e.g. cookware & water tanks. Continue reading “Flow-coating systems”
Ditmer Trading & Consulting BV may assist with sourcing critical spare, wear & tear parts for Eisenmann enameling furnaces, such as burners, radiant tubes and flue gass tiles.
The consistent liquid enamel slip properties is a critical parameter at any automated wet application process.
Unfortunately enamel rheology is known to change easily under the influence of particle size, specific weight, temperature, milling additives and/or pretreatment chemicals.
Failure to maintain its properties within measurable tolerances, may result in inconsistent enamel layer thickness and eventually even enamel defects.
Do you really believe that you can “feel it” with your fingers as demonstrated on the picture below, or do you rather prefer a more precise testing method ?!
The Italian National Unification institute has published UNI 11734 as of December 6, 2018.
This standard specifies a method for measuring the hydrogen diffusion coefficient in order to determine the fish-scale susceptibility of steels, which can be used in the enamelling process. Continue reading “UNI 11734 : Determining fish-scale susceptibility of enameling steel”
Impact fusion of powder paint may cause contamination issues at the cyclone of multicolour powdercoating systems.
It is therefore advisable to inspect and if necessary clean the ducting & cyclone of your powdercoating booth regularly.

Precise powder enamel application with a robot has many benefits, such as :
– lowest specific enamel consumption
– strongly reduced over-spray
– small factory footprint
Below a short video of a recently commissioned system for baking ovens with Nordson Encore PE spray gun and Encore LT gun controller by Noto Finishing.
With ultrasonic thickness measurement, you may detect the thickness of individual layers within a multi layer coating.
This may be of great help, when troubleshooting e.g. a two coats / one fire vitreous enameling process.
See our webshop for more details about this and other film thickness gauges.
